IMPROVEMENT IN LAM P-BURNERS.

Specification forming part of Letters Patent No. 214.353, dated April15, 1879; application filed January 18, 1879.

To all whom it may concern:

Be it known that we, G. A. BEEMAN and H. S. RAMSEY, of Comanche, in theState of Texas, have invented a new and valuable Improvement inLampBurners; and we do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a perspective view of myimproved lampburner. Fig. 2 is a side view thereof. Fig. 3 is a detailview of the cap and sleeve, and Fig. 4 is a vertical central section ofthe burner.

This invention has relation to improvements in lamp-burners, the objectof which is to prevent explosions; and the nature of the inventionconsists in combining with a lamp-base and a wick-tube supportedthereon, the said base communicating with the oil bowl, a cap fittingsnugly over the base and a sleeve attached thereto and passing over thewicktube, whereby, as the gas accumulates in the bowl, it will passthrough the tube in the base under the cap, raising the same, causingthe flame to be extinguished before the release of the explosive gases,as will be hereinafter more fully set forth.

In the annexed drawings, the letter A designates the base of alamp-burner secured in the usual way to the oil'receptacle and providedwith a wick-tube, B. Extending vertically through the base is a tube, a,the object of which will be hereinafter explained.

In the body of the base a horizontal recess of annular form is made, inwhich is seated a suitable packing-ring, b, that forms a gastight jointbetween the said base and a capvalve, 0, passed over it. This cap isprovided with a sleeve, D, that includes the wicktube, as shown in Fig.4, and, when the said cap is down, terminates on a level therewith. Thewick is raised by the usual appliance c.

As the explosive gases accumulate in the bowl they pass up under thecap-valve G, and, a sufficient force or pressure being created, the saidcap is raised. causing the sleeve to pass up over the wick-tube andextinguish the flame. The cap being raised sufficiently to cause itslower edge to clear the ring b, the gases escape harmlessly, the flamehaving been extinguished previous to said escape.

S indicates a metallic spring secured to the base below the cap-valveand extending up somewhat above the same. This spring is provided with anotch, n, that engages the rim of the cap and holds it in place underordinary circumstances, and with a head, h, at its upper end, whichchecks the rising of the said cap when raised by the gases, and preventsit from being cleared from the base. By re'racting this spring the capmay be readily lifted off of the base and the tube a utilized forreplenishing the lamp.

What we claim as new, and desire to secure by Letters Patent, is

l. The combination, in a lamp-burner, with a base, A, having awick-tube, B, and passage a, of a cap, 0, fitting over said base andprovided with a sleeve, D, inclosing the wicktube, substantially asspecified.

2. The combination, with a lamp-burner base carrying a wick-tube andprovided with an independent gas passage, of a cap valve fitting on saidbase, provided with a sleeve embracing the tube, and adapted to beraised by the pressure of the gas in the bowl, substantially asspecified.

3. The combination, with the base A, having tube B and passage a, of acap, 0, having sleeve 1), a spring, S, having notch nand head h, andsecured to the base below the cap, substantially as specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
